Few places are as safe from hazards as Countryside: it beats 89% of Canadian towns
Wildfire barely registers for Countryside, at 0% of the land within 25 km since 1986 (0.000% a year). Earthquake risk in Countryside is ordinary: NRCan’s model puts building losses at $0.030 a year per $1,000 of value, close to the typical town’s $0.030. Fewer homes than usual carry radon here, 0% over the guideline where the typical town has 6.6%. Hazard risk gives Countryside a grade of A, from earthquakes and radon alone.
What stands out about Countryside’s hazards
For Countryside, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Countryside: A
Seismic risk and radon set Countryside’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #105 of 866 in Ontario and #417 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Countryside: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Countryside’s homes, from the national burned-area record, with the fuel within 5 km.
In a typical year 0.000% of the land near Countryside burns; the typical Canadian town sees 0.000%, and both are low.
The forest starts beyond town: 0.2% of the land within 5 km of Countryside’s homes is forest fuel, against 6.6% within 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Ontario · highest of 871
Fire has taken almost none of the land around Countryside, as for 638 of the 871 towns in Ontario; Sioux Lookout tops the list at 0.16%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Measured against 2,610 towns, Countryside is in the largest group, low (92%), and at its floor, while 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Toronto Regional Conservation Authority has mapped flooding for Countryside (1 study)
What Canada’s Flood Map Inventory lists for Countryside: who studied flooding and where to see their maps.
One study on the inventory touches Countryside, Toronto Regional Conservation Authority’s from 2021, and its area can be large, so it says a map exists, not that the town floods.

Towns with a flood study on file
69% of towns in Ontario have a flood study, more than Canada’s 58%; Countryside has one too.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Countryside.
The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”

Expected shaking damage in Countryside: $0.030 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
At $0.030 per $1,000, Countryside’s earthquake risk is the typical Canadian town’s $0.030.
Shaking damage a year per $1,000 of building value
At $0.030, Countryside is below the typical town in Ontario ($0.043); Alexandria is highest at $0.21.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Neither high nor low for Canada: 48% of the 2,611 towns expect more damage than Countryside.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Only shaking damage to buildings in Countryside is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Get ready for what Countryside faces
Practical steps for Countryside’s hazards, most pressing first.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Countryside takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Countryside.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Countryside.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Countryside’s included.
